Eric Milles commented on GROOVY-10355:
--------------------------------------
[~olofasbrink] If you are using Groovy 3, you can still use the antlr2 parser
if you are not using any of the new syntax features. Otherwise, this is
something that needs to be fixed in the antlr4 parser, which is not my area of
expertise.
> Compiler interpret variable name as class name when in parentheses.

> Key: GROOVY-10355
> URL: https://issues.apache.org/jira/browse/GROOVY-10355
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 3.0.8, 4.0.0-rc-2
> Environment: JDK 11.0.12
> Reporter: Olof Asbrink
> Priority: Major
>
> This behavior seems unexpected:
> {code:java}
> String b = "B"
> System.out.println("A" + (b) + "C")
> {code}
> Throws this exception:
> {code:java}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup
> failed:
> /tmp/repo1.gm: 2: unable to resolve class b
> @ line 2, column 26.
> System.out.println("A" + (b) + "C")
> ^{code}
> However these examples work:
> {code:java}
> String b = "B"
> System.out.println("A" + b + "C")
> {code}
> and
> {code:java}
> String b = "B"
> System.out.println("A" + (b))
> {code}
